Abstract
The invention relates to a coil element for a data carrier with an integrated circuit and noncontacting coupling and to a method for producing it. The coil element includes a carrier film or layer (6) and a wire-wound coil (2) fixed to the carrier layer (6). The carrier layer (6) serves to mechanically stabilize the wire-wound coil (2) and becomes part of the card body during production of the data carrier, for example an IC card. The coil (2) is fixed to the carrier film (6) during the winding process or directly following the winding process. The winding process and the apparatus used therefor are designed so that a plurality of coils (2) can be wound and fixed on a common carrier layer (6) simultaneously.
Claims18
A coil element for a data carrier with an integrated circuit and noncontacting coupling, wherein the coil element comprises a wire-wound coil (2) and a coil carrier layer (6) for mechanical stabilization of the coil (2), the coil (2) being substantially completely wound and mounted on the coil carrier layer (6) separate from any data carrier and fastened to the coil carrier layer (6) during the winding process or directly after the winding process separate from any data carrier.
A method for producing coil elements for a data carrier with an integrated circuit and noncontacting coupling, comprising the steps of winding at least one coil (2) substantially in its entirety on a carrier layer (6) separate from any data carrier for mechanical stabilization of the entire coil (2) and fastening the coil to the carrier layer (6) during the winding process or directly after the winding process separate from any data carrier.
An apparatus for producing coil elements for data carriers with integrated circuits and noncontacting coupling, comprising a receiving plate (9) for receiving a carrier layer (6) for mechanical stabilization of wire-wound coils (2), at least one winding core (10) for winding the coils (2), at least one wire guide (11) for bringing a wire (13) near the winding core (10), and a device that produces an eccentric motion of the receiving plate (9) relative to the wire guide (11).
A multiple-copy sheet for producing data carriers with integrated circuits and noncontacting coupling, the multiple-copy sheet comprising a carrier layer (6) having wire-wound coils (2) disposed thereon, which wire wound coils are wound on the carrier layer (6) and fastened substantially in their entirety to the carrier layer (6) during the winding process or directly after the winding process.
A data carrier including multiple data carrier layers, an integrated circuit and a non-contacting data coupling, said data coupling including a coil element comprising a wire-wound coil (2) and a coil carrier layer (6) for mechanical stabilization of the coil (2), the coil (2) being wound, mounted and fastened substantially in its entirety on the coil carrier layer (6) separately from the data carrier layers, before it is associated with the data carrier.
